Europa is a character in SolarBalls, who is one of the Galilean moons along with Io, Ganymede, and Callisto. She is implied to be dating Ganymede. Europa is confident and usually agrees with whatever Ganymede says, however she is easily annoyed. When she is annoyed, she will speak in a sarcastic or mocking tone. She is also quite brave. She can look fierce and intimidating. She once threatened Ganymede to not call anyone "babe" again in a distortedly demonic voice while her eyes glowed red.
